GASOLENE OR VAPOR ENGINE.

SPECIFICATION forming part of Letters Patent No. 570,500, datedNovember` 3, 1896.

Application led November 1,1895. Serial No. 567,600, (No model.)

To @ZZ whom, it may concern:

Be it known that I, ENOCH PROUTY, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Gasolene or Vapor Engines, ofwhich the following is a specification.

My invention relates to gasolene or vapor engines.

The object of my invention is to produce a gasolene or hydrocarbonengine of a simple, eicient, and durable construction, that will operateeconomically, utilizing to the best advantage thc power generated by theexplosion of the compressed air and vapor mixture, and at the same timesecuring the proper admixture of air with the vapor, so as to producethe best results, and having a sensitive and effective means forgoverning and controlling the speed of the engine and also the feed ofthe liquid hydrocarbon to the engine, according to 'the varyingrequirements of the load or mechanism driven by the engine.

My invention consists in the novel devices and novel combinations ofparts and devices herein shown and described, and speciiied in theclaims.

In the accompanying drawings, forming a part of this specification, andin which similar letters of reference indicate like parts throughout theseveral views, Figure l is a side elevation of a hydrocarbon-engineembodyingmyinvention. Fig. 2is a front view. Fig. 3 is a section on theline 3 3 of Fig. 2. Fig. et is a detail elevation of the governor. Fig.5 is a section on the line 5 5 of Fig. 4. Figs. 6 and 7 are det-ailelevations of the cam which is moved or controlled by the governor bywhich the feed-pump is operated, showing the sliding cam in differentpositions; and Fig, S is a detail plan or face view of this cam. Fig. 9is a detail sectional view of the vaporizing-chamber and showing thepositive cut-oit or gate in the gasolene or hydrocarbon feed passage orpipe at ornear the discharge orifice or nozzle. Fig. l0 is a detailsectional view of the feed-pump. Fig. ll is a detailsectional view ofthe powdercharge starting device Jfor the engine. Fig.

l2 is a detail sectional view of the stationary Fig. 13

contact-piece of the electric igniter.

is a detail sectional view of the muffler device through which theexhaust is finally discharged from the engine and by which the noise ofthe exhaust discharge is diminished. Fig. lt is a detail sectional viewof the piston, and Fig. l5 is a detail view ot the friction-clutchmechanism on the driving-shaft of the engine.

In the drawings, A represents the frame of the engine; B, its piston; C,its cylinder; D, the driving shaft, having` a crank D', connected by apitman-rod D2 to the piston B, and E E are the ily-wheels, one beingarranged,preferably,on each side of the cylinder.

The piston B is provided with the customary metallic packing-rings b,and with annular channels or grooves b for receiving an oil orlubricant, and with a series of solid, compressed graphite plugs ordisks b2, rigidly and firmly inserted in suitable cavities bored in thepiston to receive such graphite lubrieating-plugs. are preferablyarranged in two or more annular rows b4 b4, extending around thecylinder.

The cylinder C is furnished with a water jacket or chamber C to preventthe cylinder from overheating. F is the movable contactpiece, and F thestationary contact-piece, of the electricI igniter. The stationarycontactpiece F consists of a metal pin connected with the electriccircuit F2, and insulated from the engine by a tubular bushing F3 oflireclay or other insulating material, surrounded with an asbestos orother packing F4 where it enters the port of the engine, and which isheld in place by a metallic cap F5, rigidly sccured to the engine bybolts FG. The movable contact-piece F of the electric igniter consistsof a sliding baror rod which is moved into contact with thecontact-piece F by means of the spring f, and separated therefrom by apositive-acting mechanism, preferably a cam d on the cam-shaft D3, sothat the two electrical connections F F may be thus brought yieldinglyinto connection with each other with the fixed and definite degree ofpressure due to the tension of the spring and then positively separatedyby the operation of the cam or otherlike positively-acting mechanism,thus insuring with certainty the proper making and breaking of thecircuit to The series of graphite plugs IOO produce the requisite sparkto cause the ignition of the gas. As the two contact-pieces are broughttogether by the spring the making of a perfect electrical connectionbetween them on the one hand or the prevention of jamming or injuringthe contact-pieces on the other hand does not depend upon the adjustmentof the cam or positive mechanism for moving the movable contact-piece.

G is the valve-chamber, G the inlet-valve, and G2 the outlet or exhaustvalve. The valves G' G2 are normally held closed by springs g g', actingagainst the valve-stems The spring g', which holds the exhaustvalve G2closed, is made sufficiently stronger than the spring g, that holds theinlet-valve G closed to cause the inlet-valve only to be opened by thesuction of the cylinder when the piston B is making its outward stroke,so that the air and vapor can only be drawn into the cylinder throughthe inlet. The exhaustvalve G2 is opened and held open to permit thedischarge of the exhaust from the cylinder C by means of a cam d on thecam-shaft D3 of the engine, and which engages an antifriction-roller g4on the stem g3 of the valve G2.` The springs g g' are mounted in closedguides or caps g5 Q6, attached to the valve-chamber shell, and whichalso form closed bearings for the valve-stems g2 g3 to reciprocate in.Although these guides or caps which contain the springs are closed, thesprings are not injuriously affected by the heat, as the valvestemsclose the communication with the valvechamber approximately tight.

H is the vaporizing-chamber, connected directly with the valve-chamber,and H is the gasolene or other liquid hydrocarbon feed passage or pipe,the same terminating in a nozzle or feed-orifice 7L inside thevaporizingchamber H. This nozzle or feed-orifice h projects, preferably,upward or toward the inletvalve, and is preferably of an annular form,so that the liquid will be separated into a thin annular sheet as it isdischarged from the same. The feed-passage, or the portion thereofconnected directly with the annular feed-orifice 7L, is preferablyformed in a cylindrical plug h by forming a central bore h2 through thesame, and a radial bore h3 communicating with the central bore and withthe annular orifice 7L, so that the periphery of the plug may form theinner wall of the annular orifice. The outer wall of the annular orificeis preferably formed by a sleeve 724, surrounding thev plug 71.

K is the positive cut-off or gate for closing the feed-passage H at ornear its discharge orifice or nozzle. This positive cut-off or gate maybe of any desired construction suitablefor performing this function. Ithowever preferably consists of a sliding pin or piston reciprocating inthe central bore h2 of the plug h and operating to close thefeed-passage at the radial bore h2. It is closed and held normallyclosed by a spring K. It is opened by the 'stroke of the feed-pump Mthrough the pressure of the hydrocarbon or liquid against the gate orcut-off overcoming the pressure of the spring K. As the feedpassage isthus positively closed by a gate or valve near the feed-orifice theinstant the required quantity of liquid is forced into theVaporizing-chamber by the feed-pump, the forcible suction of the airthrough the vaporizing-chamber is thus prevented when passing thefeed-orifice from drawing or sucking the gasolene or hydrocarbon fromthe feedpassage and thus occasioning irregularities in the quantity fedat each successive time or stroke.

The feed-pump M, which operates to inject the gasolene or hydrocarbon infixed and regular charges or quantities, as required, into thevaporizing-chamber, communicates with the reservoir containing theliquid or with the pipe M leading thereto, and also with the feed pipeor passage H', leading to the vaporizing-chamber I-I. This pumppreferably consists of a cylinder in which iits a piston M2, furnishedwith an adj Listing-screw m to regulate the stroke of the piston andthus the quantity of liquid fed at each movement. The piston of the pumpis operated in one direction by a spring M3 and in the other directionby a cam d2 on the cam-shaft D3, which engages an antifriction-roller mon a guide-rod m2, connected with the piston of the pump by an arm m3.

N is the governor, the saine comprising, preferably, a disk or wheel Nand two diametrically opposite weights N2 N2 on quadrant-arms N3N3,which are pivoted at n to the disk and which are connected to theopposite arms of an oscillating lever N4 on the calnshaft D3 by means ofpivoted links N5 N5. The weights or Weighted arms are pulled toward eachother by springs NG N6 and are forced apart by centrifugal action as thedisk revolves. Connected to the weights are a pair of slides N7 N 7,that engage the tapering end d4 of the sleeve clicarrying thepumpoperating cam cl2. to reciprocate on the cam-shaft D3, so as tothrow the cam cl2 into and out of engagement IIO The sleeve d? isadapted with the roller m' on the pump-actuating l slide. The roller mand the cam cl2 are both made cone-shaped or Haring, so that a veryslight sliding movement imparted to the sleeve d5 by thegovernor-operated slides N7 N7 will sufce to move the sharp or taperingedges of the cam d2 and roller m into engagement or past each other, andthen the further revolution of the cam, by reason of its tapering orinclined face, will itself operate to further reciprocate the sleeve d5and thus bring the cam d2 into full and proper engagement with theroller m. A very slight movement of the governor will therefore serve tocontrol the pump and the consequent feed of hydrocarbon to the engine,so that I am thus enabled to keep the engine under perfect control. Aspring N8 serves to move the reciprocating sleeve d5 in the oppositedirection to that in which it is moved by the governor-actuated slidesN7 N7.

The sound-muffler P consists, essentially, of a chamber preferablyseveral times the capacity of the cylinder, into which the exhaust isled through a pipe P' from the exhaustvalve, and which is furnished withan interwoven wood-slat and wire-screen bottom or side, there beingpreferably several thicknesses of wire screen or netting interwoven orinterlaced with the wood slats, and through which the exhaust passes,and by which the force of the exhaust-blast is broken, scattered, ordissipated. The muiiier-chamber P is preferably of wood.

The powder-discharge starting device comprises a metallic thimble,charger, or cartridge R, having a slot r at its upper side to permitignition of the powder therein, in connection with anexternally-screw-threaded socket or receiver R for the cartridge, whichis securely fixed to the cylinder by threaded bolts or screws r at theopening R2 in the cylinder, and an internally-screw-threaded cap R3,which serves to hold the cartridge R securely in place while beingfired. The cartridge-receiver R and the cap R3 are furnished each with atouch-hole opening r2, registering with the slot r, through which thepowder in the cartridge may be conveniently ignited by a match instarting the engine.

The driving-shaft D of the engine is provided with a loose gear orpulley S thereon, which is adapted to be gradually clutched to thedriving-shaft, so as to revolve therewith, by means of twofriction-disks S/ S2, one on each side of the gear or pulley S, both ofthe disks being keyed so as to rotate with the shaft, and one or both ofthem, preferably one, being so keyed to the shaft that it may slidethereon while rotating therewith. These two disks S S2 haveslightly-beveled or coneshaped outer faces s S, and they are forcedtogether, so as to frictionally clamp the gear or pulley S between them,by means of a rotatable spool or wheel S3, having two bevelfaced flangesor collars s s2, adapted to engage the bevel-faces s s of the disks SS2. The flanged wheel or spool S3 is moved into and out of engagementwith the disks S S2 by means of a clutch-lever S4, connected by apivoted rod or link S5 with the spool S3 or its hanger S6. I preferablyemploy two spools S3, the same being connected together by the commonhanger-bar S6, one end of the hangerbar being connected by a pivoted armor link S7 with the frame and the other end of the hanger-bar beingconnected by the link S5 with the clutch-lever Si. The clu'tch-leverS4is provided with a pawl SS, engaging a ratchet S9, the pawl beingoperated by a pawl-lever connected by a link with the pawl. As one ofthe disks S S2 is on eachvside of the gear or pulley S, it will beobserved that though the friction between the disks and the pulley isproduced by a pressure in the direction of the axis of the driving-shaftthis'pressure on the shaft is nevertheless equally balanced. There istherefore by this arrangement no side pressure or end thrust on thedrivingshaft or crank-shaft of the engine tending to interfere with theproper operation of the piston in its cylinder or to produce friction orwear between these parts. As this clutch operates gradually and byfriction to transmit the power of the engine to the gear or pulley S,the gear and pulley or machinery or mechanism to which it is connectedmay be rotated at any speed desired, whatever the speed of the engine,and any amount of power desired transmitted, by simply moving theclutch-lever.

T is a tank or reservoir for holding the Water for cooling or keepingdown the temperature of the 'cylinder C by circulation through thewater-jacket C' thereof. This tank has an open top and is locateddirectly over the engine-cylinder, and communicates with the top of thewater-jacket thereof by a number of straight direct passages or pipesT', extending directly through the bottom ofthe tank, so that whateversteam may be generated in the water-jacket may escape directly into andthrough the body of water in the tank, and thus prevent any pressure orconnement of the steam in the water-jacket or in the pipes or passagesleading from the water-jacket to the tank. A pipe T2 leads from thelower end of the tank to the lower portion of the waterjacket, thusbringing the cooler water from the bottom of the tank directly to thelower portion of the water-jacket, while the hotter or heated water atthe upper portion of the water-jacket C is continuously dischargeddirectly into the open pan or tank T, from which the vapor can freelyescape and thus permit the water to cool. By this means the water in thetank is prevented from being overheated, and at the same time acomparatively small tank or reservoir of Water is rendered fullyadequate to keep down the temperature of the cylinder, as required.

The cam-shaft Dis driven at half the speed of the crank or driving shaftD by gears U and U.
